Generating revocable fingerprint template using minutiae pair representation

With the growing concern for secure and private information protection, several issues pertaining to the traditional biometric authentication system such as the reissuance of biometric template and template security have been raised. To resolve these limitations, many new concepts of revocable biometrics have been introduced. However, the design of a template protection scheme that fulfils all the security and privacy criteria, namely revocability, non-invertibility, and anonymity, is still a challenging task. In this paper, we present a secure fingerprint template protection scheme by using minutiae pair representation that extends the concept of revocable biometrics. The proposed method integrates template with its discriminative helper data to achieve acceptable equal error rate (EER) of near 0%. Apart from performance, the security and privacy issues such as revocability and non-invertibility are also discussed.
